.SH NAME
usb_other_speed_cfg_descr \- USB other speed configuration descriptor
.SH SYNOPSIS

.SH INTERFACE LEVEL
illumos DDI specific (illumos DDI)
.SH DESCRIPTION
The \fBusb_other_speed_cfg_descr_t\fR configuration descriptor defines how
fields of a high speed device's configuration descriptor change if that device
is run at its other speed. Fields of this descriptor reflect configuration
descriptor field changes if a device's speed is changed from full to high
speed, or from high to full speed.
